Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, based on the examples herein, which are within the scope of the invention as defined by the claims, will be within the scope of the invention as defined by the claims.
As shown in fig. 1 and 2, the conventional S-type pipe-laying ship stinger 100 includes a stinger bracket 110 and a plurality of second idler sets 120 fixed to the stinger bracket 110, and each second idler set 120 includes two roller bodies arranged in a V-shape to support a flexible pipe. The stinger 110 is a square frame and comprises rigid pipes such as two stinger girders 111, a plurality of stinger beams 112, two stinger stringers 113, a plurality of stinger support beams 114, and girder connection beams 115. Because the existing interval between two adjacent second roller sets 120 is large, and the flexible pipeline with the balancing weights is heavy, the technical problem that the flexible pipeline with the balancing weights is damaged by deformation or blocked between the two adjacent roller sets after being paved on the second roller sets 120 on the stinger 100 exists, and therefore, the technical scheme in the embodiment of the application aims to solve the technical problem as follows:
As shown in fig. 3 to 5, an assembled idler assembly 200 is applied to the conventional S-type pipelaying vessel stinger 100. The assembled idler assembly 200 includes a fixed mount 220, a first idler set 230, and a support 210.
As shown in fig. 4, the fixing frame 220 is a frame structure, and is used for installing and fixing the first carrier roller set 230. After the first roller set 230 is fixed on the fixing frame 220, the first roller set 230 can support the flexible pipeline with the balancing weight. As shown in fig. 5, the supporting members 210 are located below the fixing frame 220, and the number of the supporting members 210 is plural, and the supporting members 210 are disposed at intervals to support different positions of the fixing frame 220. And the lengths of the plurality of supporting members 210 are all adjustable, and can be extended or shortened as required. The plurality of supporting members 210 are detachably connected to different positions of the fixing frame 220 at one end in the length direction, the plurality of supporting members 210 are detachably connected to the stinger 100 at the other end in the length direction, specifically, the part of the supporting members 210 are fixedly connected to one stinger main beam 111 of the stinger 100 at the other end in the length direction, and the other part of the supporting members 210 are fixedly connected to the other stinger main beam 111 of the stinger 100 at the other end in the length direction. The length adjustment of the support 210 can drive the fixing frame 220 and the first roller set 230 to move. So that the height of the first roller set 230 is adjusted to a position matching the height of the second roller set 120, so as to support the flexible pipe.
As shown in fig. 3 and 6, when in use, after the fixing frame 220, the first roller set 230 and the supporting members 210 are connected and fixed to form the roller assembly 200, the roller assembly 200 is then disposed between two adjacent second roller sets 120 on the existing S-shaped pipe-laying ship stinger 100, and the plurality of supporting members 210 are respectively and fixedly connected with the two roller frame main beams 111, so that the roller assembly 200 and the stinger 100 are fixed and the second roller sets 120 are located between the two adjacent first roller sets 230. Then, the length of the supporting member 210 is adjusted, so that the height of the first roller set 230 is adjusted to be matched with the height of the second roller set 120. Because the first roller set 230 is disposed between two adjacent second roller sets 120 and can play an auxiliary supporting role on the flexible pipe, the degree of bending deformation of the flexible pipe between two adjacent second roller sets 120 due to suspension is reduced, and further the problem that the flexible pipe is damaged or blocked between two adjacent second roller sets 120 is avoided, meanwhile, the installation height of the first roller set 230 can be adjusted by adjusting the length of the supporting piece 210, so that the optimal installation height is achieved, and the flexible pipe support is suitable for the stingers 100 with different specifications.
It should be noted that, since the spacing between the second idler sets 120 on the existing stinger 100 is fixed, the spacing between each two adjacent second idler sets 120 is too large, and thus the above-mentioned assembled idler assembly 200 is fixed between each two adjacent second idler sets 120. In addition, according to the different pitches of the adjacent second carrier rollers on the stinger 100 with different specifications, one assembled carrier roller assembly 200 may be disposed between every two adjacent first carrier roller groups 230, and a plurality of assembled carrier roller assemblies 200 may also be disposed. And, a plurality of idler assemblies 200 disposed between two adjacent first idler sets 230, preferably the first idler sets 230 on the plurality of idler assemblies 200 are disposed in spaced apart relation. Of course, the first idler sets 230 on the plurality of idler assemblies 200 disposed between two adjacent first idler sets 230 may also be adjacent or even in close proximity to each other, if desired. In this embodiment, two assembled idler assemblies are provided in the S-lay vessel stinger 100 in spaced relation between adjacent idler units.
In addition, since one end of the S-shaped pipe-laying ship stinger 100 is installed on the pipe-laying ship, and the other end of the S-shaped pipe-laying ship stinger 100 extends into water and is in a suspended state, the fixing frame 220, the first carrier roller group 230 and the supporting piece 210 of the assembled carrier roller assembly can be detached and carried independently, so that in the installation process, the S-shaped pipe-laying ship stinger 100 can be assembled in a one-step splicing manner, and the installation process is more convenient.

The first locking device 213 includes a bolt and a nut, and is connected to the nut and tightened after sequentially passing through any one of the aligned first and second connection holes, thereby connecting and fixing the first and second support bars 211 and 212, and preventing the first and second support bars 211 and 212 from moving relatively, thereby fixing the relative height of the idler assembly 200.
In some embodiments, the sliding connection between the first support rod 211 and the second support rod 212 may be a sliding manner of a sliding chute, that is, a T-shaped slot or a dovetail slot is provided on either the first support rod 211 or the second support rod 212, and a T-shaped block corresponding to the T-shaped slot or a dovetail block corresponding to the dovetail slot is provided on the other support rod of the first support rod 211 or the second support rod 212, so as to realize the relative sliding between the first support rod 211 and the second support rod 212.
